Abstract : Studies of paramagnetic relaxation in crystals were made. The results include: 1) More accurate relaxation data characteristic of the vacancy-type defects in crystal line quartz. 2) Relaxation data characteristic of similar defect centers in Ge02 Glass. 3) Interpretations of these data in terms of a large local strain at frequencies characteristic of mechanical resonance modes localized around the defect. 4) Discovery of a temperature dependence determined by the high frequency local mode associated with atomic hydrogen trapped in calcium fluoride. 5) Discussion of relaxation theory by means of relaxation diagrams, analogous to those introduced in quantum electrodynamics by R. P. Feynman. (Author)
